Hypericum plant named ‘Esm Wet’

ABSTRACT

A new and distinct cultivar of  Hypericum  plant named ‘Esm Wet’, characterized by its compact, upright and uniform plant habit; vigorous growth habit; uniform and freely flowering habit; uniform and high density of fruits; pale orange to greyed yellow-colored fruits; and tolerant to wind and rain.

Botanical designation: Hypericum androsaemum.

Cultivar denomination: ‘Esm Wet’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum, botanically known as Hypericum androsaemum and hereinafter referred to by the name ‘Esm Wet’.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program is to create new pot-type Hypericum cultivars with numerous attractive fruits.

The new Hypericum originated from a cross-pollination in February, 2000 in El Quinche, Pichincha, Ecuador of a proprietary selection of Hypericum androsaemum identified as code designation Line 48, not patented, as the female, or seed parent with a proprietary selection of Hypericum androsaemum identified as code designation Line 55, not patented, as the male, or pollen, parent. The new Hypericum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in El Quinche, Pichincha, Ecuador.

Asexual reproduction of the new cultivar by vegetative cuttings in El Quinche, Pichincha, Ecuador, since August, 2000, has shown that the unique features of this new Hypericum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Esm Wet have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Esm Wet’. These characteristics in combination distinguish ‘Esm Wet’ as a new and distinct cultivar of Hypericum:

-   -   1. Compact, upright and uniform plant habit.     -   2. Vigorous growth habit.     -   3. Uniform and freely flowering habit; uniform and high density         of fruits.     -   4. Pale orange to greyed yellow-colored fruits.     -   5. Tolerant to wind and rain.

Plants of the new Hypericum differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Hypericum are shorter than plants of the         female parent selection.     -   2. Fruits of plants of the new Hypericum are broader than fruits         of plants of the female parent selection.

Plants of the new Hypericum differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Hypericum are shorter than plants of the         male parent selection.     -   2. Plants of the new Hypericum are more vigorous than plants of         the male parent selection.     -   3. Plants of the new Hypericum and the male parent selection         differ in fruit color as plants of the male parent selection         have brown-colored fruits.

Plants of the new Hypericum can be compared to plants of the cultivar Esm Bonaire, not patented. In side-by-side comparisons conducted by the Inventor in El Quinche, Pichincha, Ecuador, plants of the new Hypericum differed from plants of the cultivar Esm Bonaire in the following characteristics:

-   -   1. Plants of the new Hypericum were shorter and had shorter         internodes than plants of the cultivar Esm Bonaire.     -   2. Plants of the new Hypericum were more freely branching than         plants of the cultivar Esm Bonaire.     -   3. Plants of the new Hypericum flowered earlier than plants of         the cultivar Esm Bonaire.     -   4. Plants of the new Hypericum had smaller leaves and fruits         than plants of the cultivar Esm Bonaire.
